When we first assembled this cage I was very surprised at how big it is! It's huge. My ferrets have room to run all over and play. The doors open very wide so it's very easy to clean which I love. You can also use the ladder to section off the two cages which came in handy while introducing the new baby. The only thing I was a little upset with was that the trays came in chipped on the sides and has some cracks in them. I'm sure I'm going to have to replace them shortly because every time I take them out they crack a little more. Other then that I am very pleased with this cage.
